The AOI-DFB-1xxx-C5-2-A-xx-x-x-xx is a multi-quantum well (MQW) distributed feedback (DFB) laser for analog applications, especially for CATV return channel.
These lasers offer high output power, wide operating temperature range, high linearity and side-mode rejection.
The hermetically sealed TO-56 packages are a cost-effective design for light sources for intermediate-reach and long-reach applications in analog transmission technology.
